- Versatility: Can be used for power or signal applications.
Applications:
- Power supply connections: Commonly used for connecting Li-ion or Li-poly batteries to electronic devices like RC hobbies, drones, and small robots.
- Sensor connections: Suitable for connecting various sensors like temperature, pressure, or light sensors to microcontrollers for data acquisition.
- Inter-board connections: Can be used to connect two PCBs for modularity or signal transmission.
- DIY electronics projects: Ideal for breadboard prototyping or custom electronics builds due to its compact size and ease of use.
Development:
- The JST XH series connectors were developed by JST Manufacturing Co., a leading manufacturer of electrical connectors.
- These connectors are constantly evolving, with improvements in materials and contact designs for better performance and reliability.
- New variants with higher current ratings or integrated features like locking mechanisms may emerge in the future.
Additional Considerations:
- While the typical current rating is 3 Amp, it’s crucial to consider the wire gauge and application for safe operation.
- For higher current applications, consider using larger JST connector series like JST PH or JST SH.
- Proper crimping techniques are essential for reliable connections with female connectors that have crimp terminals.
